JP6461371B2 - Incoming terminal state analysis method and apparatus, and program realizing the same - Google Patents

Description

  The present invention relates to an incoming terminal state analysis method and apparatus, and a program that implements the method.

  When the calling terminal inputs the telephone number of the receiving terminal, the wired telephone network or the mobile communication network requests a call to the receiving terminal. When the receiving terminal accepts the call, the call is connected between the transmitting terminal and the receiving terminal. If the receiving terminal is busy, the receiving terminal is turned off, or the user of the receiving terminal refuses the call, the call is not connected, but instead is set by the carrier on the receiving terminal side. The guided sound source is transmitted to the transmitting terminal.

  A company that makes calls to a large number of parties, such as a call center, calls a receiving terminal for efficient management, and when a receiving terminal responds, a counselor uses a transmitting device that connects to correspond to the other party.

  A conventional transmitting device receives sound source data that informs the state of a receiving terminal in frame units in real time. At this time, the conventional transmitting device detects the starting point of the sound source, analyzes the sound source data after the starting point (pattern comparison and voice recognition), and determines the state of the receiving terminal. Therefore, the conventional transmitter recognizes the intermediate point of the actual sound source as the start point, especially when the initial reception data is lost due to the analysis error due to the performance of the start point detector. Asynchronous cannot accurately analyze the status of the receiving terminal. In addition, when the callee refuses to receive, the sound source provided by the communication carrier appears after the call connection tone set individually for each call receiving terminal, so the conventional device for analyzing the sound source based on the starting point is It is difficult to analyze the call rejection status. In addition, since the conventional apparatus recognizes voice (for example, during a call) included in the received data and analyzes the state of the receiving terminal, the amount of calculation for voice recognition is large.

However, the present invention can be implemented in various different forms and is not limited to the embodiments described herein. Further, in order to clearly describe the present invention in the drawings, unnecessary portions for explanation are omitted, and similar portions are denoted by similar drawing reference numerals throughout the specification.

  In the entire specification, when a part “includes” a certain component, this means that the component may further include another component, unless otherwise stated, unless otherwise stated. means.

  FIG. 1 is a flowchart of a method for analyzing the state of a receiving terminal according to an embodiment of the present invention, FIG. 2 is a diagram illustrating a method for extracting sound source feature information according to an embodiment of the present invention, and FIG. FIG. 4 is a diagram illustrating a method of analyzing a state of a receiving terminal according to an embodiment of the invention, and FIGS. 4 and 5 respectively illustrate a method of analyzing a call rejection state of the receiving terminal according to an embodiment of the present invention. It is a figure to do.

  Referring to FIG. 1, a state analysis device (hereinafter referred to as “analysis device”) 100 of a receiving terminal stores characteristic information of a state guidance sound source provided by a communication carrier according to the state of the receiving terminal (S110). For example, as shown in Table 1, after the call connection request to the receiving terminal, the receiving terminal is in a call state, when the receiving terminal is powered off, or when the receiving terminal rejects the call, In response, other sound sources are provided for each carrier.

  The analysis apparatus 100 extracts feature information of each state guidance sound source based on a beep (BEEF) / tone (Tone) included in the sound source. Referring to FIG. 2, the analysis apparatus 100 extracts a beep / tone from a sound source including a beep / tone, position information (P) where the core sound source of the state guide sound source exists based on the beep / tone, and the length of the core sound source. Information (W) and the sound pattern (PT) of the core sound source can be stored as feature information. For example, when the receiving terminal which is a subscriber of the company S is busy, the analysis apparatus 100 states that “Because the customer is busy, it can be recorded after a beeping tone and a call charge is incurred. (BEEP) sound "may be received. As shown in FIG. 2, the analysis apparatus 100 includes position information (P) where a core sound source (for example, a sound source corresponding to “busy”) exists from a beep, length information (W) of the core sound source, and sound of the core sound source. The pattern (PT) can be stored as the characteristic information of the guidance sound source during the call of the S company. The core sound source can be variously set for each sound source.

  After requesting a call connection to the receiving terminal, the analysis apparatus 100 receives a sound source provided by the communication carrier according to the state of the receiving terminal (S120).

  The analysis apparatus 100 detects a beep / tone from the received sound source (S130).

  Based on the beep / tone of the received sound source, the analysis apparatus 100 extracts a position where the core sound source of each state guidance sound source exists from the received sound source as an analysis section (S140). For example, when the analysis apparatus 100 receives a sound source as shown in FIG. 3, the analysis apparatus 100 analyzes from the received sound source an analysis section (for example, 11, 12) in which a core sound source of at least one state guidance sound source (S1 to S9) exists. , 13, 14, 15) are extracted. Here, at least one of the state guidance sound sources (S1 to S9) is a candidate sound source. For example, when the core sound source of the state guide sound source (S1) is located at a position P1 from the beep, the length of the core sound source is W1, and the sound pattern of the core sound source is PT1, the analysis apparatus 100 starts from the beep of the received sound source. The section (W1) at the position of P1 is extracted as the analysis section 11 corresponding to the state guidance sound source (S1).

  The analysis apparatus 100 calculates the degree of coincidence between the pattern of the received sound source and the core sound source related to the corresponding analysis section for each analysis section (S150). There may be various methods for determining whether two sound sources match, and here, comparison of sound source patterns will be described. For example, since the analysis section 11 is a section corresponding to the core sound source of the state guidance sound source (S1), the analysis apparatus 100 compares the pattern of the reception sound source of the analysis section 11 and the core sound source of the state guide sound source (S1). If the analysis section 12 is a section corresponding to the core sound source of the state guidance sound source (S2), the analysis apparatus 100 compares the received sound source of the analysis section 12 with the pattern of the core sound source of the state guide sound source (S2). That is, if the received sound source is a guidance sound source during the call of the S company, the analysis section 11 has the core sound source of the state guidance sound source (S1). There will be no core sound source of (S1).

  The analysis apparatus 100 determines the state of the receiving terminal based on the degree of matching of the analysis section pattern (S160). That is, if the received sound source is a call sound source during the call of Company S, the core sound source (for example, “busy”) of the call sound source during call (S1) exists in the analysis section 11 and the analysis section 12 is turned off. There will be a core sound source (eg, “power off”) of the guide sound source (S2) and other sound sources. Therefore, when the pattern coincidence between the received sound source and the core sound source is higher in the analysis section 11 than in the other analysis sections, the analysis apparatus 100 determines that the receiving terminal that is a subscriber to the S company is in a call state.

  In this way, the analysis apparatus 100 does not perform speech recognition from the start point of the sound source or search for a core sound source that goes back from the beep / tone, rather than searching for a core sound source located at a certain distance from the start point of the sound source. Therefore, the analysis apparatus 100 can classify the sound source regardless of the performance of the start point detector, and even if the initial reception data is lost or the sound source is added to the previous part of the state guidance sound source, the state of the receiving terminal is changed. It can be analyzed accurately.

  FIG. 4 is an example of a sound source in the call rejection state (S9) of company L. When a call connection request is being made and the user refuses the call after the call connection sound has flowed for a certain period of time, the call rejection state voice is "The customer cannot answer the call. You will be connected to the answering machine service. After connecting, you will be charged for a call. " The conventional device that analyzes the pattern of the sound source based on the starting point analyzes the entire sound source including the call connection sound because the call rejection state guidance sound comes out after the call connection sound set for each receiving terminal in various ways. Unless the voice such as “The customer cannot answer the call” is recognized, it is difficult to recognize the call rejection status guidance voice after the call connection tone set for each receiving terminal.

  In order to solve such a limitation, the analysis apparatus 100 searches for a beep from the received sound source, and based on the position and length information of the core sound source from the beep, an analysis interval (for example, 21) away from the beep. -26) is extracted. Further, the analysis apparatus 100 compares the patterns of candidate sound sources corresponding to the sound sources in the analysis section. Since the core sound source in the call rejection state (S9) of company L exists in a section that is a fixed distance away from the beep sound regardless of the call connection sound, the analyzer 100 may indicate that the receiving terminal is in the call rejection state. I understand.

  FIG. 5 shows an example of a sound source in the call rejection state (S6) of company K. When a call connection request is in progress, if the user refuses the call after the call connection sound has flowed for a certain period of time, the call rejection state guidance voice “You have called the phone you have called, but it will not come out. After a while, please try again.There is no answer, please try to call again later ", and then the tone will come out.

  The analysis apparatus 100 searches for the tone from the received sound source, and compares the sound source in the analysis section separated from the tone by a certain distance and the pattern of the candidate sound source corresponding to this analysis section. At this time, the call rejection state (S6) of company K includes a tone unlike the other states. Therefore, the analyzing apparatus 100 can analyze the received sound source by using only the feature information 31 of the state guidance sound source including the tone (for example, the call rejection guidance sound source of company K).

  FIG. 6 is a diagram illustrating an analysis interval extraction method according to an embodiment of the present invention.

  Referring to FIG. 6, the analysis apparatus 100 extracts analysis sections corresponding to the core sound source of the state information sound source from the received sound source based on the beep / tone of the received sound source. At this time, the analysis apparatus 100 may select the candidate sound sources based on the information of the received sound sources, instead of performing pattern analysis by determining all the state guidance sound sources (S1 to S9) as candidate sound sources.

  For example, it is assumed that the core sound source of the state guidance sound source (S7) exists with a length of W7 at a point away from the beep by P7. However, when the point P7 away from the beep of the received sound source is silent, the analyzing apparatus 100 does not need to compare the core sound source pattern of the state guidance sound source (S7) with the silent interval. Therefore, the analysis apparatus 100 excludes the state guidance sound source (S7) from the candidate sound sources.

  It is assumed that the core sound source of the state guidance sound source (S8) exists at a point separated by P8 from the beep and has a length of W8. However, when the point away from the beep of the received sound source by P8 is a point before the start point of the received sound source, there is no received sound source to compare. Therefore, the analysis apparatus 100 excludes the state guidance sound source (S8) from the candidate sound sources.

  As described above, the analysis apparatus 100 determines whether the analysis section is a silent section, whether the analysis section is before receiving a sound source, whether the received sound source includes a beep, or includes a tone, and provides a state guidance sound source. As a result, the amount of calculation can be reduced.

  FIG. 7 is a diagram illustrating a method for detecting the length of a received sound source according to an embodiment of the present invention, and FIG. 8 is a diagram illustrating a method for detecting a silent interval according to an embodiment of the present invention.

  Referring to FIG. 7, the analysis apparatus 100 extracts a start point and a beep / tone for each received sound source, and calculates a length from the beep / tone to the start point of the sound source. The analysis apparatus 100 can store the length of the sound source as the feature information of the corresponding state guidance sound source.

  The analysis apparatus 100 analyzes the received sound source, detects the start point and the beep, and calculates the length of the received sound source. The analysis apparatus 100 can determine the state of the receiving terminal by comparing the lengths of a plurality of state guidance sound sources provided by a number of communication carriers with the lengths of the received sound sources. When the lengths of the state guidance sound sources are different, the analysis apparatus 100 can easily determine the state of the receiving terminal by comparing the sound source length information.

  Referring to FIG. 8, the analysis apparatus 100 extracts a beep / tone for each received sound source, and obtains position information on the presence of at least one silence from the beep / tone and length information of the silence for the corresponding state sound source. It can be stored as feature information.

  The analysis apparatus 100 can determine the state of the receiving terminal by comparing the length of the state guidance sound source and the received sound source and the silent section information.

  FIG. 9 is an example of a state analysis result of another receiving terminal according to the embodiment of the present invention.

  Referring to FIG. 9, the analysis apparatus 100 analyzes the state of the receiving terminal based on the feature information of the state guidance sound source (for example, S1-S9). The feature information uses the position information where the core sound source of the state guide sound source exists from the beep / tone, the length information of the core sound source, the sound pattern of the core sound source, the length of the state guide sound source, and the silent section information of the state guide sound source. Can do.

  The analysis apparatus 100 extracts an analysis section where the core speech of each state guidance sound source exists from the received sound source based on the feature information (position and section where the core sound source exists) of each candidate sound source. The analysis apparatus 100 can output the degree of coincidence between the sound source extracted from each analysis section and the pattern of the candidate sound source related to the corresponding analysis section as a score. The higher the score, the higher the possibility that there is a candidate sound source pattern in the analysis section of the received sound source.

  For example, when the number of matching points between the KTBUSY state guidance sound source (for example, a sound source received when the KT receiving terminal is busy) and the pattern of the received sound source is the highest, the analysis apparatus 100 determines which receiving terminal is a KT subscriber. It is determined that a call is in progress (KTMobile BUSY DETECT).

  The analysis apparatus 100 extracts an analysis section corresponding to the core sound source of the state guide sound source that is the reception sound source based on the beep / tone of the reception sound source, and this analysis section may be a silent sound section. Then, the analysis apparatus 100 does not need to determine whether or not the patterns for this analysis section match. Instead, the analysis apparatus 100 excludes such guidance sound sources (SKBUSY / LGBUSY / KTOFF) from the candidate sound sources, and the analysis section corresponding to the core sound source of these state guidance sound sources (SKBUSY / LGBUSY / KTOFF) is silent. Information indicating a section (for example, -1S) may be output.

  The analysis apparatus 100 extracts an analysis section corresponding to the core sound source of a certain state guide sound source from the received sound source based on the beep / tone of the received sound source, and this analysis section may be a point before the start point of the received sound source. . Then, the analysis apparatus 100 does not need to determine whether or not the patterns for this analysis section match. Instead, the analysis apparatus 100 excludes such a state guidance sound source (KTREJ) from the candidate sound sources, and the analysis section corresponding to the core sound source of the state guidance sound source (KTREJ) as the reception sound source is the boundary of the call start point. The information (for example, -1F) indicating that it is a case where it is out of the range can be output.

  FIG. 10 is a diagram illustrating a sound source information storage unit according to an embodiment of the present invention, and FIG. 11 is a flowchart of a method for analyzing a state of a receiving terminal according to another embodiment of the present invention.

  First, referring to FIG. 10, the state guide sound source can be variously set by the communication carrier. The state guidance sound source in the case of a call / power off / call rejection includes a beep / tone. However, for example, the incoming terminal is in a state in which the incoming terminal is missing or cannot respond as in the case of overseas roaming, but the missing / overseas roaming guidance sound source may not include a beep / tone.

  Therefore, in order to analyze the various states of the receiving terminal, the analysis apparatus 100 not only extracts the analysis section corresponding to the core sound source of the state guidance sound source based on the beep / tone of the received sound source, but also starts the reception sound source. The analysis section corresponding to the core sound source of the state guidance sound source can be extracted based on the point.

  For this purpose, the sound source information storage unit 110 includes a sound source information storage unit 112 from a beep / tone and a sound source information storage unit 114 from a start point.

  The sound source information storage unit 112 from the beep / tone stores, as the feature information, the position information on the presence of the core sound source from the beep / tone, the length information of the core sound source, and the sound pattern of the core sound source for each state guide sound source. The sound source information storage unit 112 from the beep / tone can further store the length from the start point to the beep / tone (sound source length) and the silence interval information from the beep / tone for each state-guided sound source.

  The sound source information storage unit 114 from the start point stores, as the feature information, the position information where the core sound source exists from the start point, the length information of the core sound source, and the sound pattern of the core sound source for each state guidance sound source. In particular, the sound source information storage unit 114 from the starting point can store feature information of missing number guide sound sources and overseas roaming guide sound sources.

  Referring to FIG. 11, the analysis apparatus 100 detects the state of the receiving terminal by comparing the feature information of the state guidance sound source stored in the sound source information storage unit with the received sound source.

  The analysis apparatus 100 receives a sound source that guides the state of the receiving terminal (S210).

  The analyzing apparatus 100 detects the start point of the received sound source (S220).

  Based on the start point, the analysis apparatus 100 extracts an analysis section at a position where the core sound source of the primary candidate sound source exists from the received sound source (S230). Here, the primary candidate sound source may be a state guidance sound source that does not include a beep / tone, for example, a missing number guide sound source or an overseas roaming guidance sound source. The list can be changed.

  The analysis apparatus 100 compares the received sound source and the primary candidate sound source related to the corresponding analysis section for each analysis section, and determines whether or not they match the reference value or more (S240).

  If the values match the reference value or more, the analysis apparatus 100 determines the state of the receiving terminal based on the matched candidate sound sources (S242). For example, if the degree of coincidence with the missing number guide sound source is high, the analyzing apparatus 100 determines that the telephone number of the receiving terminal is missing.

  If it does not match the reference value or more, the analyzer 100 detects a beep / tone (S250). If a beep / tone is not detected, the analysis apparatus 100 determines that it is in a call waiting state.

  Based on the beep / tone, the analysis apparatus 100 extracts an analysis section where the core sound source of the secondary candidate sound source exists from the received sound source (S260). Here, the secondary candidate sound source may be, for example, a state guidance sound source such as during a call, power off, or call rejection as a state guidance sound source including a beep / tone. However, the secondary candidate sound source may be a secondary candidate according to the guidance method of the communication carrier. The sound source list can be changed.

  The analysis apparatus 100 compares the received sound source and the secondary candidate sound sources related to the corresponding analysis section for each analysis section, and extracts candidate sound sources that match the reference value or more (S270). Alternatively, the analysis apparatus 100 can extract the candidate sound source having the highest number of pattern matching points from the secondary candidate sound sources.

  When the candidate sound source is extracted, the analysis apparatus 100 determines the state of the receiving terminal based on the extracted candidate sound source (S272). For example, if the degree of coincidence with the guidance sound source during a call is high, the analysis apparatus 100 determines that the receiving terminal is currently in a call.

  If no candidate sound source is extracted, the analysis apparatus 100 determines that the call is in a call waiting state (S280). That is, since the received sound source does not include a sound source that matches the core sound source of the secondary candidate sound source, the analysis apparatus 100 can determine that the receiving terminal is in a call waiting state in which it does not respond and wait for call connection.

  As described above, the analysis apparatus 100 compares the feature information of the state guidance sound source stored in the sound source information storage unit with the received sound source to detect the state of the receiving terminal, but before determining the primary candidate sound source, the beep / tone Can be detected. Therefore, the analysis apparatus 100 detects the start point of the received sound source and waits for a beep / tone to be detected. At this time, while waiting for beep / tone detection availability, the analysis apparatus 100 extracts, from the received sound source, an analysis section where the core sound source of the primary candidate sound source exists from the received sound source. The primary candidate sound sources related to the corresponding analysis section are compared to determine whether or not they match the reference value or more.

  If it is determined that the received sound source is the primary candidate sound source before the beep / tone is detected, the analysis apparatus 100 interrupts the beep / tone detection. If a beep / tone is detected while determining whether the received sound source is the primary candidate sound source, the analysis apparatus 100 interrupts the process of determining whether the received sound source is the primary candidate sound. The process proceeds to the process of determining whether is a secondary candidate sound source.

  FIG. 12 is a flowchart of a method for updating state guidance sound source information according to an embodiment of the present invention.

  Referring to FIG. 12, the communication provider can freely change the state guidance sound source of the receiving terminal. If the sound source information storage unit cannot be updated without knowing that the state guidance sound source of the receiving terminal has been changed, it is difficult for the analysis apparatus 100 to accurately detect the state of the receiving terminal. In other words, the analysis apparatus 100 goes back on the basis of the beep / tone and searches for the position of the core sound source, so that the performance is not affected even if the initial guidance voice or signal music is added or changed. However, misrecognition occurs when there is an overall change, such as a change of the state guidance sound source or a change of the speaker.

  The analysis apparatus 100 manages the characteristic information of the state guidance sound source and the comparison result value of the received sound source (S310). The analysis apparatus 100 can store the number of matching points of the state guidance sound source pattern calculated for each received sound source, and can manage the sound source analysis result for each communication carrier based on the plurality of received sound sources. Here, a separate monitoring device can manage the comparison result value between the feature information of the state guidance sound source stored in the sound source information storage unit 110 and the received sound source.

  The analysis apparatus 100 determines whether or not the state guidance sound source can be changed based on whether or not the comparison result value has changed (S320). For example, when the call sound source (S4) of company K is changed, there is no pattern that matches the received sound source even though the incoming terminal of company K is in a call. Come out differently. That is, referring to FIG. 9, if the receiving terminal is in the KTBUSY state before, the KTBUSY state guidance sound source is extracted as the matching sound source, and the pattern matching score is normally calculated around 76 points. There are cases where the number of matching points of the state pattern shows a large deviation, or the KTBUSY state cannot be detected from various state guidance sound sources. Then, the analysis apparatus 100 determines that the KTBUSY state guidance sound source has been changed.

  When a certain state guidance sound source is changed, the analysis apparatus 100 notifies the change of the corresponding state guidance sound source (S330).

  The analysis apparatus 100 stores the changed feature information of the state guidance sound source in the sound source information storage unit 110 (S340).

  As described above, the analysis apparatus 100 monitors the number of pattern matching points with the state guidance sound source for each received sound source, and detects that there is a change in the calculation result of the specific state guidance sound source. Then, the analysis apparatus 100 can report the changed state guidance sound source to the user. After confirming the changed state guidance sound source, the user updates the feature information and stores it in the sound source information storage unit 110. Alternatively, the analysis apparatus 100 may receive an input of the changed state guidance sound source, extract a core sound source (for example, “busy”) from the changed state guide sound source, and extract feature information based on a beep / tone.

  The analysis apparatus 100 can analyze the feature information of the state guidance sound source and the comparison result value of the received sound source to quickly recognize the sound source change, and can minimize the gap of performance degradation.

  Here, the analysis apparatus 100 has been described as including a monitoring unit that monitors whether the state guide sound source can be changed. However, the monitoring unit can be realized as a separate device. The monitoring unit implemented separately receives and manages the characteristic information of the state guidance sound source and the comparison result value of the received sound source from a plurality of analysis devices (including user terminals), and information on the change of the state guidance sound source in the plurality of analysis devices. And control signals can be transmitted.

  FIG. 13 is a diagram illustrating a configuration of a state analysis apparatus for a receiving terminal according to an embodiment of the present invention, and FIG. 14 is a block diagram of a user terminal according to an embodiment of the present invention.

  First, referring to FIG. 13, the analysis apparatus 100 performs a sound source information storage unit 110, a received sound source analysis unit 130, and a receiving terminal state in order to realize the receiving terminal state analysis method described with reference to FIGS. 1 to 12. An output unit 150 is included. The analyzer 100 may further include a monitoring unit 170. The analysis apparatus 100 may further include a call connection processing unit 190.

  The sound source information storage unit 110 stores the feature information of the state guidance sound source. The sound source information storage unit 110 may include a sound source information storage unit 112 from a beep / tone and a sound source information storage unit 114 from a start point.

  The received sound source analysis unit 130 compares the feature information of each state guidance sound source stored in the sound source information storage unit 110 with the received sound source, and extracts a state guidance sound source that matches the received sound source. The received sound source analysis unit 130 extracts the analysis section of the position where the core sound source of the primary candidate sound source exists from the received sound source based on the start point, and selects the primary candidate sound source related to the received sound source and the corresponding analysis section for each analysis section. A comparison can be made to determine whether the values match or exceed the reference value. The received sound source analysis unit 130 can detect a beep / tone from the received sound source, and extract an analysis section at a position where the core sound source of the secondary candidate sound source exists from the received sound source based on the beep / tone. The received sound source analysis unit 130 may extract a candidate sound source that matches a reference value or more by comparing the received sound source and secondary candidate sound sources related to the corresponding analysis section for each analysis section.

  The receiving terminal state output unit 150 outputs the state of the receiving terminal based on the analysis result of the reception sound source analysis unit 130.

  The monitoring unit 170 manages the characteristic information of the state guidance sound source and the comparison result value of the received sound source, and determines whether or not the state guidance sound source can be changed based on the distribution of the comparison result value. The monitoring unit 170 can notify the change of the state guidance sound source. The changed feature information of the state guidance sound source is stored in the sound source information storage unit 110.

  The call connection processing unit 190 can make a call to at least one receiving terminal. The call connection processing unit 190 ends the call attempt when it is difficult to connect the call based on the result of the receiving terminal state output unit 150. The call connection processing unit 190 connects a call when the receiving terminal answers. The call connection processing unit 190 can re-send to the receiving terminal or send text mail according to the method set based on the result of the receiving terminal state output unit 150.

  Such an analyzer 100 can be included in a multi-channel transmitter. The multi-channel transmission device is a device that transmits a call to a large number of receiving terminals, and can be used in, for example, a call center system.

  The analysis apparatus 100 that performs multi-channel transmission transmits a call to a plurality of receiving terminals. The analysis device 100 analyzes the status guidance voice received from each of the plurality of receiving terminals, and if the call is difficult to connect, does not connect the call to the counselor and interrupts the call connection. When the call is connected (when the other party answers), the analysis apparatus 100 transmits the connected call to the counselor. This can reduce the time for the counselor to wait for a call connection.

  As a result of analyzing the state guidance voice received from a certain receiving terminal, if the telephone is busy or is in a power-off state, the analyzing apparatus 100 can re-transmit to the corresponding receiving terminal after a certain time. As a result of analyzing the status guidance voice received from a certain receiving terminal, if the number is missing, the analysis apparatus 100 can save and report that the corresponding receiving terminal is missing.

  Referring to FIG. 14, the user can use various contents such as information retrieval, music listening, and navigation through the user terminal. However, in order for the user to make a call, work such as listening to music is stopped and a call-related procedure is performed. Therefore, it can be seen that the user cannot wait for the other party to receive the call while listening to the call connection sound or can hear the guidance sound source provided by the communication carrier and cannot make a call with the other party. In addition, when the other party cannot talk because the power is turned off or no response is made during the call, the user may inconvenience repeatedly performing a task such as trying to talk again or sending SMS after a certain time.

  In order to eliminate such inconvenience, the state analysis method of the receiving terminal may be included in the user terminal in the form of software or separate hardware. The user terminal may be a mobile terminal with a built-in communication function such as a smartphone or a smart pad, or a vehicle information processing apparatus such as navigation.

  The user terminal 200 includes hardware including a processor 210, a memory device 220, a storage device 230, a display 240, a communication device 250, a speaker / microphone 260, and the like. Is saved. The hardware has a configuration and performance capable of executing the method of the present invention. The program (application) of the receiving terminal state analysis method of the present invention described with reference to FIGS. 1 to 14 is created in a program language and executed in combination with the hardware of the user terminal 200. The processor 210 is coupled with hardware such as the memory device 220 to drive a program, and executes a state analysis method of the receiving terminal.

  The program is implemented so that the processor 210 operates as follows.

  The program is implemented to send a call and analyze the state guidance sound source based on the state analysis method of the receiving terminal of the present invention. At this time, the program is implemented to first execute an application other than a call (for example, music playback, use of navigation, etc.) via the display 240 or the speaker / microphone 260 until the call is connected to the receiving terminal. Is done. This eliminates the need for the user to listen to unnecessary telecommunications carrier guidance sound sources and call connection sounds before connecting the calls. When the user inputs in the setting information whether the call start is displayed on the screen or is notified by audio, the user terminal 200 notifies the user of the start of the call according to the designated method.

  When the called terminal answers, the program is implemented to inform the user that the call is connected via the display 240 or the speaker 260. When the call is connected, the program is implemented so as to stop the operations such as music playback and use of navigation and switch to the call mode. That is, when a call is connected, the user terminal 200 ends the application for playing music and outputs the data received from the receiving terminal to at least one of the speaker and the display.

  If the receiving terminal does not respond for a certain time (for example, 30 seconds), the program is implemented to notify the user that there is no response via the display 240 or the speaker 260.

  The program analyzes the status guidance sound source of the receiving terminal provided by the carrier, and terminates the call attempt if the receiving terminal is in a state of calling / power off / call rejection / no answer / missing number / overseas roaming etc. To be realized. The program is realized to display and notify the status information of the receiving terminal by text or voice via the display 240 or the speaker 260 according to user settings.

  The program re-sends a call to the receiving terminal based on the time information set for each status of the receiving terminal such as busy / power off / call reject / no answer / missing number / overseas roaming and various processing methods. It can be implemented to transmit a message. For example, if the status of the receiving terminal is analyzed as being busy or no answer, the program can be implemented to re-call the call at a set time (eg, after 10 minutes). If the incoming terminal is in a power off state, the program can be implemented to send an SMS (text mail) and re-call the call one hour later. If the incoming terminal is in a call rejection state, the program can be implemented to transmit an SMS instead of a repeat call.

  Thus, when the user uses the user terminal to which the state analysis method of the receiving terminal of the present invention is applied, the call connection standby time with the receiving terminal can be reduced, the call is not connected, and unnecessary wasted time is eliminated. Can do. Also, the user terminal performs a multi-purpose function, not just a telephone function. Therefore, even if a user attempts to connect a call while a content or application is being executed using the user terminal, it is not necessary to end the content or application being executed until the call is connected. In particular, the user terminal can analyze the state of the receiving terminal and try the call again according to the state of the receiving terminal, or can send an SMS, improving the convenience of the user.

  The embodiment of the present invention described above is not realized only by the apparatus and method, but via a program that realizes a function corresponding to the configuration of the embodiment of the present invention or a recording medium on which the program is recorded. It can also be realized.

  The embodiment of the present invention has been described in detail above, but the scope of the present invention is not limited to this, and those skilled in the art using the basic concept of the present invention defined in the following claims. Various modifications and improvements, or belong to the scope of the present invention.
